IMPROVEMENT m CORN-,PLANTERS.

Specification forming part of Letters Patent No. 131,482, datedSeptember 17, 1872.

To all whom it may concern:

Be it known that I, FRANKLIN UNnnRwooD, of South Butland, in the countyof Jefferson and State of New York, have invented a new and valuableImprovement in Corn-Planters and. Cultivators; and I d3 hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being bad to theannexed drawin g making a part of this specification, and to the lettersand figures of reference marked thereon.

Figure 1 of the drawing is a representation of a plan view of the frameto which my invention is applied. Fig. 2 is a longitudinal section ofthe same. Fig. 3 is a rear view of my invention.

This invention has relation to corn-planters and consists in theconstruction and novel arrangement of the furrow-plows and theirattachments, and the seed-spouts, slide, coverers, and devices foroperating and controlling the same, all as hereinafter described.

In the accompanying drawing, Arepresents the main frame of theimplement, mounted upon the wheels 0. To the axle of one of said wheelsis attached a beveled spur-wheel,

D, engaging with a bevel-pinion, E, on the end of a shaft, F. The pinionE is loose upon the end of its shaft, and communicates motion to saidshaft, from the wheel D, by means of a clutch-coupling, 0 the slidingpart of which is connected, by means of a plate, a, to a lever, Gr,pivoted to the back partof the frame, and attached or hinged at itsinner end to a bar, H,which passes across the frame and has its forwardend so bent as to be held by a catch, i. The bar His under the controlof the driver, who may turn it away from the catch and then push forwardor backward to couple or uncouple the clutch. The forward end of theshaft F is furnished with a crank, bar, K,

the shaft F is turned vibratory motion is given to the seed-slides bymeans of the connecting devices above specified. Q designates theseed-spouts, which are held in place by means of an iron band, q,secured to the top of each, and having its ends bent forward is hingedthereby to an iron plate on the under side of the frame or the bottomboard of the adjacent seed-hoppers. The bands q are also bent orextended back, and are rigidly secured to either end of a bar or shaft,B. An arm, X, connects the bar R with a lever, W, which is pivoted tothe frame A and held in position by means of a notched catch-bar, X. Thecatch-bar is pivoted to the tongue, and is turned away from the lever bythe drivers foot when he is about to use it. T represents braces, thelower ends of which are fastened to straps t near the middle of thespouts, while the upper ends are secured by hinge-bolt to the forwardpart of the straps or bands, q, as shown. The plows U are formed uponthe lower ends of sliding loops S which are held to the front sides ofthe spouts by means of straps or bands Q which are passed around thelower ends of said spouts, and have their ends bent forward to passthrough said loops. A bolt is put through said strap outside the loop,and the latter thereby held from being detached. The plows are formedeach with two furrow-sides or mold-boards, with a knife,

m, arranged between them and extending forward in such a manner as tocut through obstructing roots or sods. Small rollers, V, de signed toserve as gages to the plows, are arranged one on either side of eachplow, and

held in place by a shaft, t passing through the loop S The loops allowsaid rollers to rise and fall with the uneven surface of the ground. Inorder to raise the plows from the ground the lever W is pulled back bythe driver and the spouts swung forward. Coverers G fastened to thelower ends of standards G are designed for the purpose of scraping downthe earth behind the plows and more thoroughly covering the seed. Thestandards G are hinged to vertically sliding arms g passing throughguides g, and connected together by means of a bar, 9 Springs h,attached to the arms 9, press against the back part of the arms G, andare designed for the purpose of throwing the coverers forward withtheiraccumulations of earth. The bar 9 is connected by slotted bars 9 tocrank-shafts it upon the forward ends of which are pinions k engagingwith racks on the under side of the reciprocating bar K. When the bar Kis operated,

the scrapers are raised and lowered so as to enable them to accumulateand cast off the earth.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. The double plow U attached to the seedspouts Q by means of theloops S in combination with the gaging-rollers V, arranged substantiallyas specified.

2. The lever W, arm X, bar R, bands q, hinged spoluts Q, and plows U,substantially as specifie 3. The coverers g hinged arms g slidingarms g,springs k bar 9 connections 9 crankshafts k pinions h, and reciprocatingslidebar K, combined substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

FRANKLIN UNDERWOOD.
